Abstract

L'invention porte sur un appareil à extraire un tissu et/ou une autre matière d'un patient. L'appareil comprend généralement un outil à main (14) et un mécanisme d'extraction de tissu (16) fixé à l'outil. Le mécanisme d'extraction de tissu (16) comprend une canule (30) présentant une extrémité distale ouverte et un diamètre extérieur inférieur à environ 5 mm ou à environ 2 mm. Le mécanisme comprend en outre un élément rotatif (34) présentant une partie distale (40) munie d'un filetage hélicoïdal. Cette partie distale de l'élément rotatif s'étend au-delà de l'extrémité distale ouverte de la canule (30) pour permettre au tissu de descendre entre les courbures du filetage hélicoïdal. L'appareil est conçu pour aspirer un tissu mou à l'intérieur de la canule (30) par rotation de l'élément rotatif, sans nécessité de recourir à d'autres sources d'aspiration.
